Custom Data Provider, Event Label list memory leak

Hi Oleg,

In VC 6.0 environment while debugging I encountered memory leaks in
Calendar Control.

For Custom data provider, I gone through SQL Sample and tried following code with no succes.

if (m_pSQLDataProvider)
    {
        m_pSQLDataProvider->Close();

        m_pSQLDataProvider->InternalRelease();
    }
    m_pSQLDataProvider = NULL;

For Event Labels, I am creating Label list and setting it using SetLabelList() function in a loop. I never deleting it.

Following code is getting executed continuously in a loop:

CXTPCalendarEventLabels * copyCalendarEventLabels = NULL;

copyCalendarEventLabels = new CXTPCalendarEventLabels();
copyCalendarEventLabels->InitDefaultValues();

for (int iCount = 0; iCount < 8; iCount++)
{
CXTPCalendarEventLabel * copyEventLabel = new
                        CXTPCalendarEventLabel(iCount,
                        clr,
                        szName);

copyCalendarEventLabels->InsertAt(iCount,
                           copyEventLabel );

}

Custom Data Provider and Event Label List

LEAKS:

1) Custom Data Provider

Hi,

Please suggest alternative or modifications if any...

Thanks Oleg.

Removed both the leaks by doing following:

1) For Label Leaks

if(NULL != m_pCalendarEventLabels)
{
       m_pCalendarEventLabels->RemoveAll();
      CMDTARGET_RELEASE(m_pCalendarEventLabels);
      delete m_pCalendarEventLabels;
      m_pCalendarEventLabels = NULL;
 }

Also I commented Out call:
//m_pCalendarEventLabels->InitDefaultValues();

Is it ok if I comment out this line?

2) For Custom Memory Provider Leaks

In the desstructor:-

CXTPCalendarData* pData = GetCalendarCtrl().GetDataProvider();

if(pData)
 {
      pData->ClearCache();
      CMDTARGET_RELEASE(pData);
      pData = NULL;
 }

If I remove ClearCache() then there is Huge leak in Data Provider and Event.

Removing those leaks, now my VC++ 6.0 IDE showing me LEAKS in following components of Codejock (I am sharing only few of those LEAKS),
Please find attached file for List of all Leaks.

Please note I am using various Codejock Components in my project such as

1) Edit Control
2) Combobox
3) Toolbar
4) Buttons

Hi,

Found the way out...

Problem with two consecutive calls to InitCommandBars();

If you are calling InitCommandBars(); in main frame then no need to call it again in Child frame.

Cheers
